To allwho'm 'it mjdconcern.'

-Be it known that I, -MAHnoN LAYNE;

a citizen of4 the United States, residin at' Houston, in the county ofHarris and t tate of Texas, have .inventedcertain new and useful Imrovements in Roller-l3ea1ir1'g ,1f'sA for Shafts, o 4which thefollowing' is a specifiv.. This .invnfion .has "hifin td roller mail.1n. J

`A further point of novelty 'lies in the arf rimgement by which theroIlers are'fpoei-` tioned on shafts supportedl at their outer iendsinsteedof'their inner end, whereby provide] 'fdevice of thecharacter described the' rollers may be, ssernbled, in close relaf tionto the Shaftand more cmnpncttxrering produced Airistill'fnrther Objectisthe connection of' thefrollers .with :t member rotating 'in the fric-`tion between the member and the siitft 'is same direction. a the shaft,Whereb reduced to a minimum; and further'. Whereby the rollers beingconnected'to n common part are cansedto follow in ,equal relation4 endi'n proper time'.

Among other 'features are the provision of eswvel-fepport for the shaftand bearing,

whereby 'the elinement ofthe shaft is pref" -served; an oilbthlubrication; and a gen-V eral simplicity and practical arrangementof-lart'sWhereby access may be readily had.

nallythe object of the invention is to that .will` 'be strong, durable,eflicient1 and simple-and -comparetively inexpensive to construct;1alsoone in which the eeveral r :partsvvillnot be likely to get out ofvorking sp lfica-tion 'andillustrated the invention has `relation to'certain nove empanying*drewingsywheein;

The .bushingextends abovenn below 'the socket -and'is provided intermediate its' lationftheretoby', lockingpin 10. :Ihe'raee plate' overhangs the socket end has itsunder 201i'V and engaged by 1 1. `lugl, `depend vSpecicetton of IiettenPatent il* Patnted 213,191.1;` y i bearingcage and-rollers' ,removed`from the 4 It i's.to be understood that the drive shnft 1 .turningr fit.It is' obvious'thattheboss and seat 5`provide -substantially u ba11`andSocket.` J' joint, the purpose of which will herein er -raoeplate 9posed at such un angle as to hold the roller inclined inward andcomparatively close at ilsiupper end to the drive Shaft. l Wish to callattention at this point to the fact that there are` no studs, axles,collars or cages 4either about the drive shaft or between the dersde ofthe web 22 of a pullev 23 disposed horizontally and surmountingt'ieupper portion of the housing. The web and ring 2l are lockedtogether by pins 24 whereh i the pulley rotates the ring. Above the wethe pulley has a split hub 25 screw threaded to engage the upper screwthreaded end por tion 26 of the drive shaft 6. threaded portion passesloosely through the hub, that is, it does not have screw threadedengagement therewith; While above the hub a nut 28 engages the shaft andrests on the hub. The hub and portion 2G are provided with vertical keyseats adapted to receive a key 27 terminating below the out and acting;to secure the pulley to the' shaft. It is ob vious that by adjusting thenut Q8, the sha ft mayJ be raised and lowered as may be desire,

t is apparent that the drive shaft is driven by the pulley, which alsorotates the bearing ring. It further to be noted that the spacer ring 164is independent and free to rotate in the direction of rotation of thedrive shaft. I wish to call attention to the construction of the`hearing rollers 20, each of which is cored out and provide-fl with. along inwardly extending huh receiving the stud 19. Thehubs are notconned on the studs by a fastening and in this way the use of nuts,Washers and spacing collars obviated.' Each roller has a 'broad flatface 30 freely fittin the track 14 While its outer ed e is bevel@ at 31to coperatie with the wel 15, but normally not contacting with saidWall, which ac'ts o'nly as a. guard to retain the rollers in the race..

One ofthe novel features of thisinvention ishthe truncated. cone shapeof the rollers 1 whereby the face 30 f each tcpersinward and thetrack,14,.and the under face of its bearing ring. 21 are correspondinglyinclined, but not parallel. The taper f .the rollers is v eny,`slightiand hasdfbeen exaggerated in the rawings. However, sufficienttaper is made to :cause lan outwand thrustfand'givea more even Wear. l

This screw ,freigegebenen the' aesclrpeimfir will be seen thaiL tho`raf-o pluto ll ie 11p| o1ted by the blushing,r 7. The rare platesupports the rollere Whlch supporttlll ringt 21, which in turn supportsthe pulley hy its web 22. The shaft G 1s supported on the pulley by thenut 28. (lonseqrn-ntly the iracheni, the real supportingr member onwwhirh all of' the said parte are carried and fin 'mailling being inturn'supported by ih; il( V: 8 in the seat 5 and a ball and socket jointformed. By reason olf this ball and sorbet joint, the bean ing parts areprevented from binding upon each other in case the shaft is sprung outof line as would be hi-` rnw il.l an undue lateral strain was placed onthe pulley 3.

While the bearing.; me r be used in varifmsf. manners` l have shown11n-.'- housinp; l mount ed on a pomp head Il?. .il the lmver end of thedepending sli'eow if, s wishing H3 Suit-l ably secured to receive fdrive shaft il.

Another feature l oi ze lo accentuate is the lubrisation of fha' l ringwhereby the liability of heath is reduced to a mini mum. At one side ofthe lower portion of the housingl 1 an enlargement 34 is provided andformedwith a vertical passage 35 terminating at its upper end under therace plate 9.v Oil supplied from a cup 36 above the hearing to the,assage by a pipe 37 threaded into the en argement at the lower end. Theoil escaping from the ase sage 35 flows into the housing, surroun ingthe rare plate 9, filling the race 13 and suhmerging' the rollers QG toa point above thc studs 19. The rollers willthue carry up the cil,luliricate the bre-.ring ring 21 and other parts, From this it will beseen that the hearing operates in e bath el oil, which may be regulatedfrom the ou 36.

lt ie to be understood :hat the pulley may he. secured on 'the ehefty atvarious points and the shaft may be used either in, position, vertical,horizontal, or at en angle.
